HENRY HOBART ROATH, OF NORWICH, CONNECTICUT.

A METHOD OF VGONSClllEtU'GTINGr STOVES.

Specification of Letters Patent o. 4:54, dated November 4, 1837.,

To all whom t may concern:

Be it known that I, HENRY H. ROATH, of Norwich, in the county of NewLondon, in the State of Connecticut, have invented a new and ImprovedMode of Constructing Stoves; and I do hereby declare that the followingis a fulland exact description.

It is of cylindrical form, made of sheet or cast iron or other propermetal of any size and height that may be required the lower part beinglined with fire brick, soap stone, or other fit substance,` the bottom.being grated and provided with a drawer (in the drawing marked Gr)vforan ash pan,^the

whole supported by legs or standing on a pedestal in the usual style. Ata convenient height from the bottom on the front side is a door (markedD) through which coal is supplied. Directly above the door is a coverwhich entirely'closes the orifice of the cylinder. Through the center ofthis cover, a pipe of proper diameter is introduced, which after passingup nearly to the upper eX- tremity of the cylinder leads 0H the smokeand vapor to the chimney above this cover which is situated nearlymidway between the top and botto-m of t-he stove, the cylinder isperforated with holes (marked C) made near each other of a diameterproportioned to the size of the cylinder and extending quite around it.Just above these holes there is ano-ther cover perforated in the centerinto which is fitted another cylinder some few inches smaller indiameter than the external cylinder and of the same height, thus leavinga vacant space between the cylinders;the pipe for conveying olf thesmoke passing up through the center of the internal cylinder. A cover isthenplaced on the top (marked A,) -itted air tight over that portion o-fthe space between the cyll inder and either partially or entirely openoverv theinternal cylinderz (that also being open at the lower end)through which the smoke pipe Vpasses discharging itself into thechimney'a little below the upper extremity of the stove. Onv each sideof the cylinder which composes the body of the stove, a pipe or smallcylinder (marked H) the diameter of which is larger or smaller accordingto the size of the stove, leading from the .vacant space under thefirstcover, immediately over the fire and passing out 'on eachv side ofthe stove is connected with the chamber in the upper part of the stovethrough the small cylinder (marked I)k at the upper points (H B, showsthe chamber for hot air; F, door to grate; D, door to furnace. y

What I claim as my own invention and not previously known in the abovedescribed stove isj The warming of the air within the stove as abovedescribed in this specication by means of the pipes on the sides of thestove, the holes or perforations around Vthe surface of the same abovethe first cover and the internal cylinder.,
